Abstract
Description
Technical Field
[0001] The present application belongs to the field of robotics technology, and more specifically, relates to a blind spot filling folding radar and an intelligent robot. Background Art
[0002] In today's technological landscape, radar, as a crucial sensor device, is widely used in intelligent robots, autonomous vehicles, and other systems requiring environmental perception and obstacle avoidance. Radar detection technology transmits and receives electromagnetic waves to measure the distance, speed, direction, and other information about surrounding objects, providing critical data for navigation, positioning, and decision-making. However, traditional radar equipment often suffers from a limited field of view, limiting its effectiveness in complex environments.
[0003] Specifically, the detection range of traditional radar is often limited by its physical installation location and structural design. On devices like intelligent robots, radars are typically fixed in place, resulting in a fixed detection angle and range. When robots need to operate in narrow or complex environments, such as indoors, in corridors, or in areas with dense obstacles, the fixed radar detection field of view may not cover all critical areas, resulting in the robot being unable to perceive potential dangers or obstacles in a timely manner, thus affecting its navigation and obstacle avoidance accuracy.
[0004] To address this issue, researchers have tried various approaches, such as increasing the number of radars and improving their beamforming technology. However, these approaches often come with increased costs, larger equipment, or higher energy consumption, hindering their widespread adoption in practical applications. In the field of intelligent robotics, in particular, size, weight, and energy consumption are significant factors affecting performance and market acceptance.
[0005] Furthermore, for intelligent robots that need to operate in diverse environments, fixed radar configurations can present another problem: the radar's detection range may be too broad on wide roads or in open areas, while it may be insufficient in narrow roads or confined spaces. This requires robots to have flexible radar configurations in different environments to adapt to varying road widths and detection requirements. Utility Model Content
[0006] The purpose of the embodiments of the present application is to provide a blind spot filling folding radar and an intelligent robot to solve the technical problem of insufficient adaptability of the existing technology in the radar detection process.
[0007] To achieve the above-mentioned purpose, the technical solution adopted in the present application is as follows: providing a blind spot filling folding radar, comprising: a housing, a radar detection unit, and a blind spot filling folding mechanism, wherein the radar detection unit is arranged outside the housing, and the blind spot filling folding mechanism is arranged inside the housing;
[0008] The blind spot filling and folding mechanism includes a fixed plate, a driving motor, a driving gear, and a driven gear. The driving motor is arranged on the fixed plate, the driving gear is connected to the output shaft of the driving motor, the driven gear is meshed with the driving gear, and the driven gear is provided with a mounting fixed shaft.
[0009] Preferably, a warning light is provided on the top of the shell, and the radar detection unit is provided on the bottom of the shell.
[0010] Preferably, a limiting sleeve is provided on the fixing plate, the output shaft of the driving motor is located in the limiting sleeve, a limiting gasket is provided on the top of the driving motor, and the limiting gasket is connected to the inner wall of the shell.

[0012] Preferably, the mounting and fixing shaft has a built-in cavity, and the cavity is used for wiring.
[0013] Preferably, the housing is provided with a linear pressure sensor, and the linear pressure sensor surrounds the side wall of the housing.
[0014] The present application also provides an intelligent robot, comprising a robot body and a pair of blind spot filling folding radars as described above, wherein the pair of blind spot filling folding radars are located on both sides of the tail of the robot body;
[0015] In the extended state, the distance between the pair of blind spot filling folding radars is greater than the width of the robot body; in the retracted state, the distance between the pair of blind spot filling folding radars is less than or equal to the width of the robot body.
[0016] Compared with the existing technology, the blind spot filling folding radar provided by the present application drives the driving gear to rotate by a driving motor, and the driving gear drives the driven gear to rotate.

[0024] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clearly understood, this application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.
[0025] It should be noted that when an element is referred to as being “fixed on” or “disposed on” another element, it may be directly on the other element or indirectly on the other element. When an element is referred to as being “connected to” another element, it may be directly connected to the other element or indirectly connected to the other element.
[0026] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.
[0027] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.
[0028] Please also refer to Figures 1 to 3 The blind spot compensation folding radar 100 provided in an embodiment of the present application is now described. The blind spot compensation folding radar 100 includes: a housing 10, a radar detection unit 20, and a blind spot compensation folding mechanism 30. The radar detection unit 20 is disposed outside the housing 10, and the blind spot compensation folding mechanism 30 is disposed inside the housing 10.
[0029] Specifically, the blind spot folding mechanism 30 includes a fixed plate 31, a drive motor 32, a driving gear 33, and a driven gear 34. The drive motor 32 is arranged on the fixed plate 31, the driving gear 33 is connected to the output shaft of the drive motor 32, and the driven gear 34 is engaged with the driving gear 33. A mounting fixed shaft 35 is provided on the driven gear 34.
[0030] It is understandable that since the radar detection unit 20 is disposed outside the housing 10 , it can reduce obstruction, allowing the radar detection unit 20 to obtain a larger detection field of view. The housing 10 can also protect the blind spot folding mechanism 30 .
[0031] When the blind spot filling folding radar 100 is fixed to the target device through the installation fixing shaft 35 , the installation fixing shaft 35 is fixedly connected to the target device, and the target device uses the blind spot filling folding radar 100 to perform space detection.
[0032] To increase the radar detection field of view, the driving motor 32 can be used to drive the driving gear 33 to rotate, which in turn drives the driven gear 34 to rotate. However, since the driven gear 34 is provided with a mounting shaft 35, when the mounting shaft 35 is fixedly connected to the target device, the reaction force will cause the blind spot compensation folding radar 100 to deflect relative to the target device, and the radar detection unit 20 will be extended, thereby increasing the radar detection field of view.
[0033] Similarly, when it is necessary to facilitate transportation or avoid collisions, the driving motor 32 can drive the active gear 33 to rotate in the opposite direction. The reaction force will cause the blind spot folding radar 100 to reset itself relative to the target device, and the radar detection unit 20 will be retracted, thereby facilitating transportation and avoiding collisions.
[0034] Compared with the prior art, the blind spot filling folding radar 100 provided in the present application drives the driving gear 33 to rotate by the driving motor 32, and the driving gear 33 drives the driven gear 34 to rotate. The reaction force will cause the blind spot filling folding radar 100 itself to deflect or reset relative to the target device, thereby achieving the purpose of folding and improving adaptability.
[0035] In another embodiment of this application, please refer to Figure 1 A warning light 11 is provided on the top of the shell 10, and the radar detection unit 20 is provided at the bottom of the shell 10.
[0036] It can be understood that by setting the warning light 11 at the top of the shell 10, it is convenient for the user to observe. By setting the radar detection unit 20 at the bottom of the shell 10, the warning light 11 and the radar detection unit 20 are prevented from interfering with each other, and the detection field of view is improved.
[0037] In another embodiment of this application, please refer to Figure 2 and Figure 3 A limiting sleeve 36 is provided on the fixing plate 31 , the output shaft of the driving motor 32 is located in the limiting sleeve 36 , a limiting gasket 37 is provided on the top of the driving motor 32 , and the limiting gasket 37 is connected to the inner wall of the shell 10 .
[0038] It can be understood that the combination of the limiting sleeve 36 and the limiting gasket 37 can jointly achieve axial limiting of the driving motor 32 and reduce noise.
[0039] In another embodiment of this application, please refer to Figure 2 and Figure 3 A slewing bearing 38 is provided on the top of the driven gear 34 , and the slewing bearing 38 is fixed on the fixing plate 31 .
[0040] It can be understood that the slewing bearing 38 can simultaneously withstand large axial loads, radial loads and overturning moments during the folding process, and utilize the reaction force to drive the displacement of the blind spot folding radar 100.
[0041] In another embodiment of the present application, the mounting and fixing shaft 35 has a built-in cavity, and the cavity is used for wiring.
[0042] It can be understood that, for example, the lines of the warning light 11, the radar detection unit 20, and the drive motor 32 can pass through the cavity, which can simplify the structure.
[0043] In another embodiment of this application, please refer to Figure 1The housing 10 is provided with a linear pressure sensor 12 , and the linear pressure sensor 12 surrounds the side wall of the housing 10 .
[0044] It is understandable that when an object located in the blind spot of the radar detection unit 20 collides with the blind spot folding radar 100 , the linear pressure sensor 12 can sense the pressure and quickly trigger the folding function to reduce losses.
[0045] Please also refer to Figure 4 and Figure 5 The present application also provides an intelligent robot 200, which includes a robot body 201 and a pair of blind spot filling folding radars 100 as described above, and the pair of blind spot filling folding radars 100 are located on both sides of the tail of the robot body 201.
[0046] In the extended state, the distance between the pair of blind spot filling folding radars 100 is greater than the width of the robot body 201 ; in the retracted state, the distance between the pair of blind spot filling folding radars 100 is less than or equal to the width of the robot body 201 .
[0047] See also Figure 4 Assuming that the distance between a pair of blind spot compensation folding radars 100 is L in the extended state, the width of the road that can pass through must be at least greater than L; Figure 5 In the retracted state, the width of the road that can be passed must be at least larger than L-ΔL, where L-ΔL is the maximum width of the robot body 201.
[0048] Compared with the prior art, the blind spot filling folding radar 100 provided in this application has a pair of blind spot filling folding radars 100 located on both sides of the tail of the robot body 201. In the extended state, the radar detection field of view can be expanded, and in the retracted state, the road width requirement can be reduced.
[0049] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
